* This file is inspired in rtems_monitor & Chris John MyRightBoot
*
* But I want to make it more user friendly
* A 'monitor' command is added to adapt the call rtems monitor commands
* at my call procedure
*
* TODO: A lot of improvements of course.
* cp, mv, ...
* hexdump,
*
* More? Say me it, please...

* The BSP Specific are not welcome here.
